A research team from the University of Chinese Academy of Sciences, Tsinghua University, Peking University, and several hospitals has developed a miniature self-powered cardiac pacemaker.
This breakthrough may extend the pacemaker’s service life to match that of the natural heart, thereby addressing the critical issue of repeat replacement surgeries and opening a new path toward lifetime maintenance-free and human-machine symbiotic implantable electronics. The key innovation of this capsule-sized pacemaker lies in its integrated energy regeneration module, which captures kinetic energy from the heart’s motion via electromagnetic induction and converts it into electrical energy.
The device also features a miniaturized design with excellent biocompatibility and hemocompatibility, enabling minimally invasive transcatheter implantation and significantly reducing surgical trauma.
In animal trials lasting one month, the pacemaker operated autonomously and consistently regulated heart rhythm.A
